PEARL-BUTTON MACHINE.

SPECIFICATION forming part of Letters Patent No. 485,338, dated November 1, 1892.

Application filed January 6, 1892. Serial No. 417,149. (No model.)

To all whom it may concern.- 7

Be it known that we, HARRY TONKS and THOMAS TONKS, citizens of the United States,

residing at Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Pearl-Button Machines; and we do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide an apparatus for cutting pearl buttons, simple in construction, durable, and easily handled, and also to provide means for sharpening the cutting-tool without removing it from its holder or interfering with the work.

The invention consists in the improved pearl-button-cutting machine and the sharpening device and the arrangement and'com binations of the various parts, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figurel is a front elevation of ouriinproved pearl-button-cutting machine; Fig. 2 is a top plan view thereof with part of it shown in section. Fig. 3 is a sectional view on line 3 Fig. 1; and Figs. 4.- and 5 are enlarged detail views of the cutting device.

In said drawings, A represents the bed plate, to which are secured in any desired manner the button-blank-holding device 13, the cutting mechanism (7, and the sharpening device D.

The button-blank-holding device consists of the frame a, in which isarranged a hollow shaft 1), adapted to be revolved by pulley c. In said shaft operates a spindle (Z, carrying the chuck-jaws This spindle and also the chuck-jaws are controlled by the lever f, operated by a trcadlc or in any desired manner and by the spiral springg. The button-blank is introduced into the chuclojaws in the 'ordinary manner.

The cutting mechanism, which is arranged on the bed-plate opposite to the above-described holding device, consists of the frame lar or washer m is secured by a screw or in 1 any desired man nor to the cutter-carrier rod k and is guided in extension h of frame 72, byits downwardly-extending arm m. The rod or spindle 7a is limited in its motion by adjustable nuts Ze 79, arranged on the threaded portion of said rod, as will be clearly seen in Figs. 1 and 2 of the drawings.

To the forward end of bar 7.; is secured or made integral therewith the cutter-head n, in which is arranged the cutter 0, extending downward and at an oblique angle to bar It. At one side of the bar L and near the cutterhead is arranged an extension p, to which" is secured a downwardly-extending screw q, provided with an adjusting or elevating wheel 9', on which rests a disk or plate .9, provided with a recess 8', in'which rests the lower end of the cutter o. This disk 5 is prevented from rotating by the screw Z, sliding in groove q of screw q,..as shown in Figs. 1 and 4.

The sharpening device is arranged at right angles to the cutting device, and so that'when the cutter is moved backward it will come in direct contact with the emery or sharpening wheel. This sharpening device consists of the emery wheel a, secured to spindle v, adapted to be revolved by pulley w in bearin g 10. To this bearing w is secured or made integral therewith a threaded rod 202, adapted to be raised or lowered in hollow post 20 by means of internally-tln'eaded hand-wheel 10 and is also adapted to be guided by screw 10*, sliding in groove 10 of rod- 10 This screw 10 also serves as a set or tightening screw after the sharpening device has been adjusted to the required height.

In operation the button-blank is inserted in the chuck after the jaws have been opened by means of lever f, operated by a treadle, and the cutting-tool, which has previously been adjusted to the required height, is then pressed against the button-blank by means of handdcver Z, and as the blank revolves it is turned to the desired form. Then the cutter is moved back-to its normal position, which brings it in contact with the emery-wheel,

the right, and thereby raises the cutter to its proper position.

- It can be clearly seen and understood that by the forward motion of the cutterthe button-blank is turned the desired shape and by the backward motion the cutter is .resharp: ened when necessary.

We do not intend to-limit' ourselves to the exact construction shown and described, as Variouschanges can be made without changing the scope of our invention. v I

Having thus'described our invention, what we claim as new, and desire to-secure by Letters Patent, is p ,7 I

1. In a pearl-button machine, the combination, with the chuck and its carrier, of a lever operating said chuck, a cutting-tool arranged opposite said chuck and adapted to be moved to and from said chuck, a lever operating said cutting-tool, means for; raising and lowering said cutting-tool,asharpening-wheelarranged at right angles to the cutting-tool, a spindlecarrying said sharpening-wheel, a threaded rod-provided at its top with a bearing for said spindle, and means for raising or lowering said rod, all said parts being arranged and adapted to operate substantially as described,

and for the purposes set forth.

2. In a pearl-button machine, the combination, with the chuck and its carrier, of 'a guide arranged-opposite said chuck, a rodlk in said guide "and provided at its forward end with a cu tter-head, a cutter arranged at'an oblique angle to and in said cutter-head, a screw extending downward .from said jrod'k and behind the'cutter,-head,"aninternallythreaded wheel arranged on said screw,- a "disk ar-- ranged upon said wheel'and'provided with a recess and adapted 'to, receive the lower end- 7 of the cutter, nuts 7c M, adj'ustablysecure'd to the rod'k and adapted to limit said rod in its .forward mqtion, anda hand-lever for'operating said rod and cutter, all said .par'tsbeing arranged and adapted to operate snbstantially as described, and for the purposes-set-forth. In a pearl-button machine, a sharpening device combining'therein a spindle, a sharp ening-o'r emery wheel secured to said spindle,

a threaded rod provided with a top, adapted to form the bearing for said spindle, an internally threaded hand wheel, arranged on and adapted to operate said threaded-rod, a groove arranged in said threaded'rod, and a hollow post receiving said rod and provided with a screw, said screw being adapted to serve as a guiding and'tightening device for .said threaded rod, all said parts being arranged and adapted to operatesub'stantially as described,'and.for the purposes set forth.-

In testimony that We claim the foregoing we have hereunto set our hands'this 23d day of December, 1891.
